A force of 20 Newtons gives a brick an acceleration of 5 m/s^2. What is the mass of the brick?

To find the mass of the brick, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).

Mathematically, this can be represented as:

F = m * a

Given that the force is 20 Newtons and the acceleration is 5 m/s^2, we can rearrange the equation to solve for mass:

m = F / a

Substituting the values into the equation, we have:

m = 20 N / 5 m/s^2

Simplifying this expression, we get:

m = 4 kg

Therefore, the mass of the brick is 4 kilograms.
